Can Threestripe Cory live with Neon Blue Rasbora?
Light caution
Why
- Only a narrow water hardness overlap — keep both around 5–5 dGH.
- Large size gap (Threestripe Cory 2.2" vs Neon Blue Rasbora 0.8") — watch that the smaller one gets its share at feeding time.
Sweet spot: both do well at 72–79°F and pH 6–6.5 — aim there.
